The purpose of this study was to explore children's experiences in a series of creative drama activities based around the use of picture books. The subjects were a total of 17 children 4 years of age. The research, implemented over the courses of 10 weeks, was integrated into their daily education curriculum. The children's drama activities were collected by participant observation, field notes, audio and videotape transcriptions, documentation of the young children's drama activities (eg. pantomimes, role plays & improvised expression, improvisations). The analysis reveals the following findings : 1) even shy and passive young children tried to participate in pantomime activities after reading books. 2) In role play & improvised expression activities, young children were immersed in the improvised situation and spontaneously expressed their emotions and thoughts as actors without the use of any scripts, in an impromptu manner. 3) In improvisation, young children collaborated with other children to create the improvisation by extending or transforming the content of the picture books through their own ideas.

2022년 중부권 폭우로 인하여 서울 강남구에서 도시홍수가 발생하였고, 많은 인명 및 경제적 지해를 유발하였다. 기후변화로 야기되는 극한 강우의 발생 패턴 및 강우 패턴의 변화가 많은 연구에서 확인되어 오고 있다. 한국의 경우 극한 강우가 국지적이고 단기간에 많은 강우량을 발생시키는 패턴으로 변화하고 있는 것으로 연구되고 있다. 특히, 도시홍수의 경우 도달시간이 매주 짧기 때문에, 초단기간에 대한 강우분석이 필요하나, 강우관측시스템의 한계로 인하여 현재까지는 초단기간에 대한 극한 강우분석이 미비한 실정이다. 1997년 이후로 기상청에서는 지속적으로 방재기상관측망(Automatic Weather System, AWS)를 설치를 하였고, 최근에 설치된 AWS의 경우 초단기간 강우량 자료를 관측할 수 있는 장비 및 시스템을 구축하고 있으나, 운영된 기간이 짧아 빈도해석에 적용하기에 한계점이 많다. 본 연구에서는 서울 지역에서 영향을 주는 40여개의 AWS의 초단기간 강우량 자료를 이용하여 서울 지역을 확률강우량을 산정하고자 한다. 짧은 관측기간으로부터 발생하는 확률강우량 추정불확실성의 저감을 위해서 지역빈도해석을 적용하였다. 지역빈도해석으로는 지수홍수법을 적용하였다. 추가적으로 서울안에서 공간적으로 확률강우량의 편차에 대하여 조사 분석하였다. 본 연구의 결과를 통하여 서울지역의 초단기간에 대한 안정적인 확률강우량의 추정이 가능할 것으로 예상되며, 추가적으로 지역별 확률강우량의 차이를 비교분석 할 수 있을 것으로 기대된다.

Nonaqueous organic electrolyte solution in commercially available lithium-ion batteries, due to its flammability, corrosiveness, high volatility, and thermal instability, is demanding to be substituted by safer solid electrolyte with higher cycle stability, which will be utilized effectively in large-scale power sources such as electric vehicles and energy storage system. Of various types of solid electrolytes, composite solid electrolytes with polymer matrix and active inorganic fillers are now most promising in achieving higher ionic conductivity and excellent interface contact. In this review, some kinds and brief history of solid electrolyte are at first introduced and consequent explanations of polymer solid electrolytes and inorganic solid electrolytes (including active and inactive fillers) are comprehensively carried out. Composite solid electrolytes including these polymer and inorganic materials are also described with their electrochemical properties in terms of filler shapes, such as particle (0D), fiber (1D), plane (2D), and solid body (3D). In particular, in all-solid-state lithium batteries using lithium metal anode, the interface characteristics are discussed in terms of cathode-electrolyte interface, anode-electrolyte interface, and interparticle interface. Finally, current requisites and future perspectives for the composite solid electrolytes are suggested by help of some decent reviews recently reported.

전 세계적인 LNG 수요 증가에 따라 LNG 운반선의 대형화 및 극한 환경의 항로 선택이 불가피해지고 있다. 이러한 상황에서 LNG의 슬로싱 현상에 따른 화물창의 구조적 안정성 여부가 큰 이슈거리로 떠오르고 있다. 슬로싱 현상에 의한 구조 안전성을 평가하는 가장 이상적인 방법은 유체 영역과 탱크의 복합적인 상호 작용을 완벽하게 구현하는 것이다. 하지만 과도한 계산 시간과 결과의 정확성이 확보되지 못한 상황에서 LNG 운반선 화물창의 안전성 평가에 적용하기에는 문제가 있다. 많은 연구 단체에서는 불규칙적인 슬로싱 압력 신호를 삼각파 등의 형태로 이상화하여 구조해석에 적용하고 있지만 이 또한 유체의 압축성 및 비선형성을 고려하는데 한계를 드러내고 있다. 본 연구에서는 슬로싱 하중을 받는 구조의 안전성을 평가함에 있어 쌍방향(2-way) FSI(Fluid-Structure Interaction)의 과도한 해석 시간 및 수렴의 어려움을 보안하고 유체의 비선형성을 고려할 수 있는 단 방향(1-way) FSI 기법을 이용하는 절차를 제안하고자 한다.

Through Korean traditional opera (changgeuk) Medea, composer Hwang Ho-jun showed eclectic music idiom by 1) writing music (jakchang) on manuscript paper and score, 2) introducing the "song-through" format, 3) including various solo melodies, 4) maximizing the effect created by a singing narrator (dochang) with the chorus master and a mixed chorus, 5) seeking an interplay of tension and release by using both discord and chord, 6) achieving the effect of kil-bakkum, the Korean traditional method of modulation, through modulation and borrowed chord of Western music. In Medea, instrumentalists adopted suseong-banju (Korean traditional accompaniment) which does not spoil the voice of singers. Hwang adopted song for the way how singers express various hidden sides of play among song, aniri (narration) and balim (gesture) and introduced the Sung-through format in which the play is comprised entirely of song. In Medea, oral sounds expressing wail, lament, cheer, sneer and scream are often used and various solo melodies appear that fit for personalities of characters, clearly showing what bunchang (singers' singing songs divided according to characters) is all about. And discord and chord are effectively used according to the development and mood of play. Hwang also achieved successfully the effect of kil-bakkum by abandoning the traditional modulation method and boldly introducing modulation and borrowed chord of Western music.

The purpose of this study is to develop a role play instruction model to increase higher-order thinking abilities in geographical education. This study reviewed the references which included the contents of higher-order thinking abilities, and discussed the educational significance and application of role play instruction model. The developed role play instruction model was applied to four classes in high school in Korea. After applying the model, this study asked some question about the model to the students which engaged in this model. Higher-order thinking essentially means thinking that takes place in the higher-levels of the hierarchy of cognitive processing. Higher-order thinking abilities contain critical thinking abilities, creative thinking abilities, problem solving and decision making abilities, meta-cognition abilities. The role play instruction model is an effective method which can increase higher- order thinking abilities. The questioning to students which engaged in the class of applying to role play instruction model provides feedback about development instruction models to increase higher-order thinking abilities.
